Abstract

The apparatus structure of the conodont Icriodus expansus Branson and Mehl is here recognised as consisting of seven element
types- I, Ca, Cb, Cc, Cd, Ce and Cf. The apparatus contains one pair of I elements and over 140 associated cone elements.
The orientation of the I element is reversed. The study is based on a large collection of fused clusters found in a sample
from the Upper Devonian (Frasnian) Napier Formation in the Oscar Range of the Canning Basin, Western Australia.
